Nitrite accumulation during denitrification with quinoline or indole as the sole carbon source
以喹啉或吲哚为单一碳源时反硝化过程中亚硝酸盐的积累

Batch experiments were conducted to investigate nitrite(NO-2-N) accumulation during denitrification with quinoline or indole as the sole carbon source and electron donor and nitrate(NO-3-N) as the electron acceptor.Significant NO-2-N accumulation was observed at all tested C/N ratios when quinoline was used as the sole carbon source,and the maximum NO-2-N accumulation percentage decreased with the increase of C/N ratio.While the maximum NO-2-N accumulation percentage reached 93.97% at C/N=2.5,it was only 42...
